Hazrat Abu Musa (May Allah be pleased with him) reported: when the Messenger of Allah [SAWW](PBUH), feared mischief from a people, he would supplicate: "Allahumma inna naj`aluka fi nuhurihim, wa na`udhu bika min shururihim (O Allah! We ask You to face them, and seek Your Protection against their evil.”

[Abu Dawud Hadith # 1537 # and An-Nasa'i Hadith # 8631].

Lesson : as mentioned above in Surah Al-Qasas Ayat 07 “when you fear for him, then cast him into the river and fear not, nor grieve. Verily! We shall bring him back to you, and shall make him one of (Our) Messengers." Allah’s Help, we are told, is a protection against all perils. Through this prayer we seek His Help with the conviction that the deceptions and designs of the infidels will turn back upon them.
